ignition coil

[36 flathead]

Anyone know if a 65 mustang coil uses 12 volt or is there a ballast resistor in circuit. I am looking for a ford coil that will work on 12 volt with no resistor

They do make a coil that has a built in resistor. The parts stores carry them.

 

[ford1]

you were told right, they make an internally resisted coil, kragens, auto zone, pep boys all carry them

The Mustang uses a resister 1.35 ohms ICR10 orICR11 at napa.
Foreign cars with 12 volts thur 69 like vw needs NO resister.

Mustang has a resistor wire in the circuit. Pink in color, even has a different feel to it because it must be heat resistant.

thanks for the information, I will check napa

 

[ford1]

its usually just as cheap to buy the resisted coil, with the resister hanging on the out side of the coil is just one more thing that can get broken,

I would suggest the Bosch Blue ignition coil , no resistor needed and has a working resistance of 3-4 ohms.
We also sell a 3-4 ohms coil as well if you cant find a Bosch unit locally......

what about a 6v high performance coil?? Dave

Don't most high performance coils have less resistance then the original coil? Made to work with electronic dizzys.
